Since then, mining has been present in this region with only a few interruptions and has left many consequences. The results of research conducted by the Geological Survey of Slovenia in areas of former mining and metallurgic activities were analysed, and areas in which the allowed concentrations of 10 officially considered heavy metals were exceeded (As, Cd, Co, Cr, Cu, Hg, Ni, Mo, Pb in Zn) were singled out. The research area comprised 466 km2 around the towns of Celje, Idrija, Jesenice and Mežica. The results have shown that the concentrations of the considered heavy metals didn't exceed the officially allowed concentrations in only 7 % of the research area. The concentrations ofheavy metals in soils exceed the official limit concentration in 18 %, warning concentration in 59 %, and critical concentration in 16 % (76 km2) of the research area. We have established that, in Slovenia, mining and ore processing represents one of the major modes for anthropogenic input of heavy metals into the environmentNa ozemlju Slovenije se je rudarjenje začelo že v bronasti dobi. Od takrat naprej se je ta dejavnost odvijala s prekinitvami do današnjih dni. V okolju je pustila številne posledice. Rezultate geokemičnih raziskav na vplivnih območjih nekdanjega rudarjenja in metalurgije, ki so bile opravljene na Geološkem zavodu Slovenije, smo na osnovi primerjalnih analiz ovrednotili in izločili ozemlja na katerih vsebnost vsaj ene zakonsko določene težke kovine (As, Cd, Co, Cr, Cu, Hg, Ni, Mo, Pb in Zn) presega uradne meje onesnaženosti. Z raziskavo smo zajeli 466 km2 površine na območjih Celja, Idrije, Jesenic in Mežice. Ta je pokazala, da so le na 7% celotne raziskane površine vsebnosti obravnavanih kovin pod zakonsko dovoljenimi koncentracijami. Na 18% raziskane površine vsebnosti težkih kovin presežejo uradno mejno vsebnost, na 59% omenjene vsebnosti presežejo opozorilno vsebnost ter na 16% (76 km2) raziskanih ozemelj kritično vsebnost težkih kovin v tleh. Ugotovili smo, da rudarstvo in predelava rude v Sloveniji predstavljata enega od glavnih načinovantropogenega vnosa težkih kovin v okolje na proučevanih ozemljihTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaGeološki zavod Slovenije
